The SetBkMode function sets the background mix mode of the specified device context. The background mix mode is used with text, hatched brushes, and pen styles that are not solid lines.
int SetBkMode(
| HDC hdc, | // handle of device context |
| int iBkMode | // flag specifying background mode |
| ); |
Parameters
hdc
Identifies the device context.
iBkMode
Specifies the background mode. This parameter can be either of the following values:
| Value | Description |
| OPAQUE | Background is filled with the current background color before the text, hatched brush, or pen is drawn. |
| TRANSPARENT | Background remains untouched. |
Return Values
If the function succeeds, the return value specifies the previous background mode.
If the function fails, the return value is zero.
Remarks
The SetBkMode function affects the line styles for lines drawn using a pen created by the CreatePen function. SetBkMode does not affect lines drawn using a pen created by the ExtCreatePen function.
The iBkMode parameter can also be set to driver-specific values. GDI passes such values to the device driver and otherwise ignores them.
